thorlin commented 6 years ago

I follow rmii clk and pinctrl code of kernel to gmac_rockchip file of uboot, but internal phy can't work.

below is uboot startup message :

Does anyone to give me advice?

support for internal phy is WIP, current U-Boot only support external phy.

Has support for the internal PHY within U-Boot been added yet? Got an application where this would be an advantage?
